Normally a granular drainage blanket is provided over the area treated with vertical drains in order to facilitate the dissipation of porewater at ground surface level. As the underlying compressible soil is usually unable to directly support construction plant, the drainage blanket should also function as a foundation platform for the construction plant. It is advisable to use a geotextile sheet beneath the drainage blanket to prevent loss of granular material into the soft deposits or a foundation failure under the load imposed by construction plant.  4, record 3, English, - horizontal%20drainage%20blanket

The need for a consolidation drainage blanket decreases rapidly with time because the rate of consolidation settlement decreases rapidly ... In a saturated soil with one-way drainage towards the ground surface, the volume of water expelled is equal to the volume of soil consolidation. [If, for example, it took 848 days to reach 90% consolidation, equal to 900 mm, on a particular site.] The design of consolidation drainage blankets is based on calculating the average consolidation drainage during 1/848 of the time for 90% consolidation, i.e. during the period when the first 3.8% of consolidation occurs.  1, record 4, English, - consolidation%20drainage%20blanket

consolidation: The process whereby the application of pressure on a soil layer over a period of time causes a reduction in its volume by expelling fluid from the pores and by packing the soil grains closer together. The amount and rate of consolidation are important factors in the computation of settlement of structures and thus their foundation design.  2, record 4, English, - consolidation%20drainage%20blanket

It has been suggested ... that since the thinnest layer of sand to act successfully as an erosion pumping filter was 25 mm, and the slurry penetrated /3mm in this case, then a geotextile with a thickness of 10 mm or more might successfully replace the sand blanket layer. The fact that the most successful sand blanket have voids ranging from 5 to 30 [micrometers] seems to suggest that the geotextile's voids should be of a similar magnitude. Erosion pumping filters, using a geotextile in conjunction with a sand blanket, are much more effective than geotextiles alone.  1, record 5, English, - sand%20blanket

Drainage sous dalle de béton [...] : matelas drainant servant à collecter et à évacuer l’eau qui pourrait s’accumuler sous une dalle de béton de sous-sol. Fonction du géotextile [...] Drain : le géotextile collecte et évacue l’eau qui s’accumule sous la dalle de sous-sol, évitant ainsi des remontées d’humidité. Filtre : le géotextile doit assurer sa propre protection contre le colmatage ou empêcher le colmatage du matelas drainant granulaire.

Geotextile nets consist of two sets of roughly round polymer strands that cross at a constant angle to give very open geotextile with large diamond or rectangle shaped apertures.
